●Start inputs: X16 and X17
X16 is used to control the start of the safety outputs as “auto start” which does not use a start
switch, or “manual start” which does not detect welding of the start switch. When the start input
(X16) is turned ON (the ON state of X16 must be kept over 0.1s) during all devices connected to
the safety inputs are in safe state, a start condition is established.
X17 is used to control the start of the safety outputs as “control start” which detects welding of the
start switch. When the start input transits OFF→ON→OFF (the ON state of X17 must be kept
during 0.1s to 5s) when all devices connected to the safety inputs are in safe state, the start
condition is established.
Note: If both of X16 and X17 are turned ON, the SafetyOne will detect an error. As a result, the
error LED displays “3” and the state changes to the Stop state. Use only X16 or X17.
●Safety outputs (with OFF-delay timer): Y0 to Y3
Y0 to Y3 function as safety outputs with the OFF-delay timer. When the timer is set to “0s”
(indication “1”), the safety outputs are shut OFF immediately.
Y0 and Y1: Safety output 1
Y2 and Y3: Safety output 2
●Safety input monitor outputs: Y4 to Y11
Y4 toY11 function as status monitors of the safety input devices connected to the SafetyOne.
When both contacts of the safety device are ON, the output is ON. When both contacts are OFF,
the output is OFF.
If an input monitor error is detected, pulses (1Hz) are sent.
Y4 outputs the status of the safety input 1 (X0-T0, X1-T1).
Y5 outputs the status of the safety input 2 (X2-T2, X3-T3).
Y6 outputs the status of the safety input 3 (X4-T4, X5-T5).
Y7 outputs the status of the safety input 4 (X6-T6, X7-T7).
Y10 outputs the status of the safety input 5 (X10-T10, X11-T11).
Y11 outputs the status of the safety input 6 (X12-T12, X13-T13)
●Safety output monitor outputs: Y12 and Y13
Y12 and Y13 function as monitor outputs that output the status of the safety outputs. When the
safety outputs are OFF, the safety output monitor output is turned OFF immediately, even if the
OFF-delay timer has been set.
Y12 outputs the status of safety output 1 (Y0 and Y1). This turns ON when Y0 and Y1 are both
ON.
Y13 outputs the status of safety output 1 (Y2 and Y3). This turns ON when Y2 and Y3 are both
ON.
